FIELD OF THE INVENTION

[0001] The present invention relates to a materials supply contract system and method for use in conducting business on-line over a network of computers such as the Internet.

BACKGROUND OF THE INVENTION

[0002] In this specification reference is made to a ‘Bill of Materials’ (BOM). A BOM may relate to the supply of goods and/or services, and for ease of reference these are generically referred to in this specification as materials. The BOM in this case is defined as the material purchase requirement, and includes the list of material items that the buyer will procure, as well as business rules, market rules, and any additional comments. A common term that may be used interchangeably with BOM in this context is ‘Lot’.

[0003] Traditionally, a buyer of materials will prepare a ‘Request For Quotation’ (RFQ) and send this to a number of potential suppliers. The RFQ is used to acquire information and pricing about strategic goods and services. An RFQ may set out not only the specification of the materials required but other details of the buyers requirements, such as supply period, payment terms, return rules, liabilities for defects, indemnities against loss, etc. In reality, offers for the supply of materials received commonly have terms of supply which vary from the stipulations of the RFQ. For example, a particular supplier may be the one to offer the lowest price for the materials, but may not accept the supply term or liabilities set out in the RFQ. For materials supply critical to the buyer, this means that considerable time and effort in direct face-to-face negotiation with a number of suppliers is needed before a final contract for supply can be realised. This is the process of awarding a tender, which process includes reviewing submissions to the RFQ, selecting a winning tenderer, and finally contract negotiations to determine the final terms of trade.

[0004] In an effort to simplify the process, it has become common for buyers to approach a number of known suppliers for a certain category of goods or services in order to establish a panel of suppliers. Suppliers are often willing to participate in a selection process for appointment to a panel where the buyer constitutes a significant on-going purchaser of these types of materials. To be appointed to the panel, each supplier enters into a standard contract which specifies the general terms of supply of materials from that supplier to the buyer. Such contracts are referred herein as base supply contracts and deal with issues such as payment terms, return rules, liabilities for defects, indemnities against loss, etc, as mentioned previously. This means that when the buyer wishes to buy certain materials, only the panel of suppliers are approached and the RFQ is significantly simplified, as is any consequent offer for the supply of those materials.

[0005] The use of base supply contracts is now prevalent in not only the manufacturing industry but also the service industry.

[0006] Notwithstanding this, considerable manual effort is still needed to coordinate the selection of a supplier.

SUMMARY OF THE INVENTION

[0007] According to a first form of the invention, there is provided a method for a buyer to award a supply contract, issued as a BOM, to a supplier selected from a panel of predetermined suppliers which each have a base supply contract with the buyer, the method being conducted over a computer network which comprises at least one buyer computer, an administrator computer and at least two supplier computers, the method comprising:

[0008] a) sending a buyer message from the buyer computer to the administrator computer identifying the BOM which includes at least one predetermined parameter (eg. material requirement, business and market rules and/or special instructions);

[0009] b) receiving the buyer message and displaying the BOM on a site on the administrator computer which is accessible by at least two supplier computers;

[0010] c) sending a BOM message from the administrator computer to at least two suppliers;

[0011] d) receiving and storing an offer message in the administrator computer from one or more of the at least two supplier computers which includes an offer to supply goods or services in accordance with the BOM;

[0012] e) sending an acceptance message from the administrator computer to the supplier computer which sent the successful offer; and

[0013] f) sending a notification message from the administrator computer to the buyer computer notifying the buyer computer of one or more of the offers.

[0014] In a preferred embodiment of the invention, the acceptance message includes a display and/or reference to the contract relating to the supply of the materials.

[0015] In a preferred embodiment of the invention, the BOM includes a time period for submissions of offers by the suppliers. The method may include the step of extending this time period, to enable submission of an improved final bid from at least some of the supplier computers from which offer messages were received.

[0016] In another preferred form of the invention, the method comprises the additional steps of establishing a panel of predetermined suppliers.

[0017] In another preferred form of the invention, the method comprises the step of addition to or removal of suppliers from the panel of predetermined suppliers.

[0018] In another preferred form of the invention, the method comprises the additional steps of comparing any offer received by the administrator computer under step (d) to prior offers received by the administration computer under step (d) and, if the latest offer is more than any of those prior offers, sending a message to the supplier computer of that supplier that a lower offer has been received by the administrator computer.

[0019] In a second form of the invention, there is provided a method for a buyer to award a supply contract to a supplier selected from a panel of predetermined suppliers which each have a base supply contract with the buyer, the method being conducted over a computer network which comprises at least one buyer computer, an administrator computer and at least two supplier computers, the method comprising the steps of:

[0020] (a) establishing key parameters for a BOM to be submitted by the administrator computer to the at least two supplier computers (eg. price, quality, delivery and service);

[0021] (b) applying a weighting to each of the parameters;

[0022] (c) applying a rating for each of these parameters for each supplier of the panel of predetermined suppliers;

[0023] (d) calculating an overall rating for each supplier of the panel of predetermined suppliers; and

[0024] (e) applying that overall rating to any offer received by the administrator computer from the supplier computer of that supplier in response to the release of a BOM to adjust that offer prior to comparison of that offer with any other offer.

[0025] In a preferred embodiment of the second form of the invention, applying a rating for each supplier in step (c) is based at least partially upon past performance of that supplier for each parameter. These include objective and subjective parameters such as previous timeliness of delivery of materials, quality of delivered materials, freight, price etc. In another preferred embodiment of the second form of the invention, the step of applying a rating for each supplier in step (c) is based at least partially upon other parameters outside the control of that supplier for each parameter, such as forecast material demand, commodity price forecasts, exchange rate forecasts, industry trends, historical bidding data, etc.

[0026] Typically the first and second forms of the inventions will be used in combination to optimise the overall system.

[0027] The method may include the step of providing to each supplier computer a ‘current bid to win’ (CBTW) in respect of said supply contract, the CBTW calculated by said administrator computer to dynamically indicate to a supplier the offer that that supplier must submit to compete with the best previous offer. The CBTW for supplier may be calculated in accordance with the formula:

CBTWx _(m) =FB _(n−1)−(MD/SFx)

[0028] where x indicates a particular suppliers X; m indicates that particular supplier's bid number; n indicates the overall bid number (ie 1^(st) bid:n=1; 2^(nd) bid:n=2; etc); FB indicates a factored bid for said particular supplier; MD indicates a set minimum bid decrement; and SF is the supplier factor set in accordance with said overall supplier rating. In a preferred embodiment, FB is calculated in accordance with the formula:

FB _(n) =SBx _(n)+(MD/SFx)−MD

[0029] where SB is a submitted bid.

[0030] The method may include the step of setting a reserve price for award of said supply contract, wherein no acceptance message can be sent for an offer that fails to comply with said reserve price.

[0031] The invention as defined above gives a business buyer access to a potentially powerful web-based procurement application that may be completely internally controlled by the buyer. Unlike most current procurement applications, the invention does not need to be third party controlled. The invention is adapted to be initialised, updated, and controlled by the procurement specialist within the buyer organisation.

[0032] It may also be optimally used for critical material procurement. However, use for non critical material procurement is also possible.

[0033] The invention is most suited to the procurement of critical materials usually sourced as an input directly into the manufacturing or production process. In this environment, the invention applies dynamic pricing theories in a critical procurement environment subject to complex contracts and long-standing buyer/supplier relationships.

[0034] Procurement of critical materials is considered a core competence of the buying organisation and is not normally out-sourced.

[0035] The business philosophy behind the invention is that the buyer will normally select a panel consisting of a number of approved suppliers for material categories listed in a production or manufacturing BOM. As mentioned previously, traditionally, the buyer would identify suitable suppliers, then conduct an expensive tendering process to select a supplier for a multi-year contract.

[0036] The invention makes it possible for the buyer to establish an underlying base supply contract with multiple approved suppliers upfront, with no need to conduct a tendering process again. That is a panel of approved suppliers from which a buyer proposes to source its materials. Those contracts may be without limitation of period, or may have a fixed period. In theory these are base supply contracts which should only need to change when the buyers basic material needs change.

[0037] The procurement specialist within the buyer now can focus on the strategic role of maintaining the optimum panel by approving a new supplier to join the panel, or by removing a supplier from the panel which does not meet the preferred supplier basic requirements.

[0038] Once the supplier panel is established, and the base supply contract for each panel member is in place, the buyer simply releases a new BOM to the panel who will view and validate the BOM before conducting an online bidding event. During the bidding event the panel of suppliers will bid against each other for the right to supply the BOM.

[0039] The buyer is responsible for selecting, approving, rating and contracting with suppliers. An administrator computer external to the buyer may be used as a service to the buyer and generate a detailed report based upon past bidding events to aid with the supplier selection and rating. Basically, the buyer is in control of the procurement function, which is especially important for the procurement of direct materials (mission-critical or competitor-sensitive).

[0040] Significantly, the method and system of the invention allows the buyer to enter supplier ratings before a particular bidding event, these ratings then being modified on an ongoing basis between successive events to reflect a changing relationship between a buyer and the supplier panel members. Once a bidding event is complete according to the rules of that event, there is no post-event discussion before the contract is awarded, because the unique approach to automatic comparison of bids during the process itself precludes the need for such a process, thus providing a considerably stronger dynamic to the method than hitherto available. As discussed above, unlike some known auction models, which effectively outsource a buyer's supply needs to a third party procurement function, the present invention allows the buyer to retain the required control over the process.

[0041] The invention will be especially useful where the materials are specifiable (for example, the material item can be specified using an industry accepted code), contestable (multiple approved suppliers), and of sufficient value to justify the bidding process.

[0042] In summary, the system is commenced by a primary interaction between the buyer computer and the administrator computer. In this primary interaction, the buyer creates a supplier panel category/sub-category for a particular material type usually listed in a BOM.

[0043] The buyer forms a base supply contract with each supplier in the panel sub-category. The terms of the base supply contract will usually be identical for all panel suppliers. The base supply contract is usually an open-ended (no time limit) contract that specifies all requirements other than price, quantity, material, and some specific business rules such as payment terms, delivery terms, payment method etc. A unique base supply contract identifier for each supplier is recorded in an administrator computer against the panel sub-category identifier.

[0044] When the buyer is ready to release a BOM, it selects a panel of preferred/approved suppliers from the prescribed approved suppliers that are qualified to meet the minimum requirements (quality, warranty, service, delivery etc) as defined by the buyer.

[0045] In one particularly preferred form of the invention, each approved supplier will be given a rating report against qualitative criteria such as quality, service, warranty, etc in a proportion based on the importance of the qualitative criteria to the buyer. This aggregated supplier rating is the input to a factoring algorithm, where the qualitative criteria are reduced to a percentage scaling factor. This system is explained later in more detail.

[0046] This supplier unique percentage scaling factor, and the supplier specific ratings against the qualitative criteria, are usually only visible to the buyer and the particular supplier so rated, therefore allowing the supplier to work on increasing their individual assigned percentage factor by improving quality, service, warranty terms, etc. The reason a particular supplier will work to increase their rating is that this has a direct effect on their submitted bid, therefore allowing a higher actual bid to match a supplier who has been assigned a higher factor. By continuously reviewing each supplier's rating reports, and by analysing recorded bidding data, the buyer is able to optimise the supplier panel to achieve the best cost saving during the bidding event. This process is referred to as ‘panel optimisation’.

[0047] Via the buyer computer, the buyer inputs into the administrator computer the dynamic business rules, such as payment, delivery terms, etc, which are not defined in the base supply contract, but are instead entered against each BOM in the administrator computer.

[0048] The buyer may now also forecast material demand, and optimise the BOM (using factored inputs such as material requirements forecasts, commodity price forecasts, exchange rate forecasts, industry trends, historical bidding data etc) to maximise the potential material cost saving from the active bidding process. This process is referred to as ‘BOM optimisation’ and is discussed later in more detail.

[0049] The BOM is then released by the administrator computer by sending a message to the supplier computers of the selected panel suppliers, who are then able to actively bid against the BOM under the buyer-defined market rules.

[0050] The supplier that has submitted the lowest factored bid to the administrator computer at the completion of the bidding time will be declared the winner.

[0051] A dynamic contract between the winning supplier and buyer is now formed by the administrator computer, and the details, including supplier name, material description, quantity ordered, and price achieved, are stored within the administrator computer. This contract is associated with the base supply contract already in place with the winning supplier.

[0052] The buyer will draw down (each purchase order issued against the dynamic contract will decrement the dynamic contract quantity) from the dynamic contract either manually or via a connected online purchasing application or via the client Enterprise Resource Planning (ERP) application.

[0053] In an alternative form to the above, the invention may involve a ‘factored pricing’ process, analagous to the factored bidding process. Factored pricing allows the buyer to apply factoring before an RFQ or BOM is released to prospective suppliers. Alternatively, where a supplier has the ability to vary one or more of the terms of contract (eg. payment terms), or to vary one or more of the specification criteria (eg. quality), this may be used for supplier self factoring before a bid is actually finalised.

[0054] In this form of the invention, there is provided a method for a buyer to award a supply contract to a supplier selected from a panel of predetermined suppliers which each have a base supply contract with the buyer, the method being conducted over a computer network which comprises at least one buyer computer, an administrator computer, and at least two supplier computers, the method comprising the steps of:

[0055] a) establishing parameters for an RFQ to be submitted by the administrator computer to at least two supplier computers, one of said parameters being price;

[0056] b) applying to the price, for each supplier of the panel of predetermined suppliers, a rating, in order to arrive at a factored price for each said supplier;

[0057] c) providing the RFQ and the respective factored price to each supplier of the panel of predetermined suppliers; and

[0058] d) receiving an offer message in the administrator computer from one or more of at least two supplier computers which includes an offer to supply goods or services in accordance with the RFQ and the factored price.

[0059] In this way, the buyer can be notified that an RFQ has been accepted in accordance with the factored price and prescribed other parameters.

[0060] This form of the invention will typically be used in combination with the first form, to provide a bidding system using factored pricing parameters.

[0061] The buyer may choose either to award the contract on the first acceptance response received from a supplier at or below the factored price, or to award it to the supplier's which sets the lowest price below that supplier's factored price. In either case, the factored price becomes the basis of the contract offer.

[0062] Preferably, the rating for each supplier is based at least partially upon past performance of that supplier. That can depend on considerations such as timeliness of delivery, quality, service record, etc.

[0063] In a preferred form, the method includes the step of, for at least one of said parameters;

[0064] establishing a range of possible values of said parameter, each of said values being associated with a certain weighting factor; and

[0065] providing said range of values to each supplier of the panel of predetermined suppliers.

[0066] Preferably, the rating applied to the price for each supplier is determined in accordance with said weighting factor, and may be provided to the respective supplier.

[0067] In this way, a relationship is established between each value and the applicable weighting factor. Each value represents an option for selection by a supplier, the respecting options each having a respective weighting factor which will affect the rating to be applied to arrive at that supplied factored price. This may be done automatically once an option is selected by the supplier, or the weighting factor may be provided to the supplier who may then ‘self factor’ in selecting an option.

[0068] According to the invention in yet another form, there is provided an administrator computer system for enabling a buyer to award a supply contract, issued as a BOM, to a supplier selected from a panel of predetermined suppliers which each have a base supply contract with the buyer, the system operating over a computer network and connecting to at least one buyer computer and at least two supplier computers, the system including:

[0069] a) means for receiving, from a buyer computer, a buyer message identifying the BOM, the message including at least one predetermined parameter (eg. material requirement, business and market rules and/or special instructions);

[0070] b) means for displaying the BOM on a site associated with the administrator computer which is accessible by at least two supplier computers;

[0071] c) means for sending a BOM message to one or more of the at least two supplier computers;

[0072] d) means for receiving and storing an offer message from one or more of the at least two supplier computers, the offer message including an offer to supply goods or services in accordance with the BOM;

[0073] e) means for sending an acceptance message to the supplier computer which sent the successful offer; and

[0074] f) means for sending a notification message to the buyer computer notifying the buyer computer of one or more of the offers.

[0075] The system preferably includes means for comparing any offer received by means (d) to prior offers received by means (d) and, if the latest offer is more than any of those prior offers, sending a message to the supplier computer of that supplier that a lower offer has been received by the administrator computer.

[0076] According to the invention in yet another form, there is provided an administrator computer system for enabling a buyer to award a supply contract to a supplier selected from a panel of predetermined suppliers which each have a base supply contract with the buyer, the system operating over a computer network and connecting to at least one buyer computer and at least two supplier computers, the system including:

[0077] (a) means for establishing key parameters for a BOM to be submitted to the at least two supplier computers (eg. price, quality, delivery and service);

[0078] (b) means for applying a weighting to each of the parameters;

[0079] (c) means for applying a rating for each of these parameters for each supplier of the panel of predetermined suppliers;

[0080] (d) means for calculating an overall rating for each supplier of the panel of predetermined suppliers; and

[0081] (e) means for applying that overall rating to any offer received by the administrator computer from the supplier computer of that supplier in response to the release of a BOM to adjust that offer prior to comparison of that offer with any other offer.

[0082] Preferably, the system includes means for providing to each supplier computer a current bid to win (CBTW) in respect of said supply contract, the CBTW calculated by said administrator computer to dynamically indicate to a supplier the offer that that particular supplier must submit (at or below) to compete with the best previous offer.

[0083] According to the invention in yet another form, there is provided an administrator computer system for a enabling a buyer to award a supply contract to a supplier selected from a panel of predetermined suppliers which each have a base supply contract with the buyer, the system operating over a computer network and connecting to at least one buyer computer and at least two supplier computer, the system including:

[0084] a) means for establishing parameters for an RFQ to be submitted to the at least two supplier computers, one of said parameters being price;

[0085] b) means for applying to the price, for each supplier of the panel of predetermined suppliers, a rating, in order to arrive at a factored price for each said supplier;

[0086] c) means for providing the RFQ and the respective factored price to each supplier of the panel of predetermined suppliers; and

[0087] d) means for receiving an offer message from one or more of at least two supplier computers which includes an offer to supply goods or services in accordance with the RFQ and the factored price.

[0088] The system in this form may include means for, for at least one of said parameters;

[0089] establishing a range of possible values of said parameter, each of said values being associated with a certain weighting factor; and

[0090] providing said range of values to each supplier of the panel of predetermined suppliers.

DETAILED DESCRIPTION OF THE INVENTION

[0091] The following description outlines integrated embodiments of the invention which combine different forms of the invention. The explanation is for illustration purposes only and does not restrict the scope of the invention in any way. The description that follows refers to the accompanying drawings which diagrammatically illustrate various features of the system described. In particular, FIGS. 1-12 illustrate the functional requirements of the system and method described, whilst FIG. 13 depicts the various components (and their interrelation) of the system in operation.

[0092] A. System Overview

[0093] The described system provides for users an online environment to prepare for, conduct and review bidding for BOMs.

[0094] There are three distinct users of this network system—buyers via buyer computers, suppliers via supplier computers and administrators via administrator computers—and hence three different views of information.

[0095] A buyer will be able, via its buyer computer, to create BOMs, distribute them to the supplier computers of selected suppliers and then watch the bidding process take place. At the end of the bidding process, the buyer will know they will be buying at the best price from one of their selected suppliers. Supporting functions such as creating and maintaining BOMS, creating and maintaining supplier lists, viewing summary details of BOMs, viewing active BOMs, viewing pending BOMs, and finding old BOMs through a history function, will be available to buyers on the buyer computer and/or by access to the administrator computer.

[0096] A supplier will be able to participate, via its supplier computer, in bidding for BOMs that a buyer has invited them to bid for. Competing suppliers will actively bid against each other in a competitive network environment for the right to supply a BOM to the buyer. Supporting functions such as viewing the BOM, validating the BOM, viewing Pending BOMs, and finding old BOMs through a history function, will be available to suppliers on the suppliers computer or by access to the administrator computer.

[0097] The buyer and their selected suppliers will be able to have access to, and view, bidding for a BOM on the administrator computer.

[0098] Administrators by operation of the administrator computer will be responsible for entering in account details for suppliers and buyers. It is only when the administrator computer does this that the buyer computer or supplier computer will have access to the administration computer.

[0099] The administrator of the administrator computer will also have privileged access to the system so that they are able to view any BOM information, or view any active BOMs that may be in the middle of a bidding process. The administrator may of course be within the buyer organisation. The administrator computer will also need to associate suppliers to buyers and will also be able to run activity and account reports.

[0100] B. Requirements

[0101] This section describes functionality for the invention which is designated hereafter as Dynamic Pricing Solution (DPS). There are three sections to the DPS. There are the buyer functions, supplier functions, and administration facilities (The system overview is shown in FIG. 1).

[0522] It is the responsibility of the Administrator to associate suppliers with a buying company.

[0523] All account information for the suppliers must be in the system before suppliers can be associated with the buyer. Multiple suppliers will be associated with a single buyer.

[0524] The administrator will be able to find a buyers supplier list by searching by use of filters:

[0525] Company name (any buying company)

[0526] Contract number

[0527] Account number

[0528] A list of suppliers associated with the buyer will then be displayed. The administrator will then be able to remove a supplier from the list or add a new supplier to the list.

[0529] Note that buyers will only have access to suppliers that they are associated with.

[0530] (iv) Privileged Account for System Access

[0531] A user with access to this account will be able to view BOM information for any account on the system.

[0532] They will have access to the Active, Pending, History and Supplier details for any buyer account. Note, the Company Name will be displayed on the screen in the place of Authority as shown to the buyer.

[0533] 8. Security Requirements

[0534] User Id and Password access provide security for system access by users. Encryption and Digital Certificates may additionally be used to authenticate users of the application.

[0535] 9. Factored Bidding

[0536] As mentioned above, factored bidding will allow the buyer to set supply criteria for a particular subcategory of materials. Each material subcategory (panel) can have different supply criteria. For example Toyota might, for a category ‘Camry’ and subcategory ‘Tyres’ set supply criteria as price, quality, delivery, and service. Whereas, for Toshiba, manufacturing laptop computers, the category ‘Satellite Pro’ and subcategory ‘LCD Display’ might have supply criteria of warranty, quality and price.

[0537] Once the actual criteria are identified, the buyer will numerically rate the importance of each of the identified criteria, eg from a scale of 1 to 10 (the scale itself is not important as long as the rating is representative of the importance of the criteria in an absolute and a relative sense).

[0538] As a purely fictional scenario, Toyota might set: price—9, quality—7, delivery—8, and service—6, out of a maximum score of 10 for each criteria established against Camry/Tyres.

[0539] Toshiba might set warranty—9, quality—7, price—5, once again out of a maximum score of 10, for each criteria listing established against Sattelite Pro/LCD displays established criteria.

[0540] The next stage is for the buyer to consider how well each panel supplier for the specific subcategory is performing or should be rated (from historical interactions) against each of the identified criteria.

[0541] Toyota could have 3 suppliers that can all supply Camry tyres to the required specification ie Toyota has 3 approved Camry tyre suppliers that will form the panel for the Camry Tyres subcategory in the administrator computer. The three might be Dunlop, Michelin, Bridgestone. Toyota creates the following supply matrix. Criteria Rating Dunlop Michelin Bridgestone Total Price 9 5:00 8:00 4:00 00 Quality 7 7:49 3:21 6:42 70 Delivery 8 9:72 5:40 7:56 80 Service 6 7:42 4:24 8:48 60 Total 28:163 20:85  25:146 210 Factor 0.776 0.405 0.695

[0542] Note. Price can be specified so that the supplier knows how important price will be in the selection process. The rating that the buyer gives each supplier on price is good feedback to the supplier about how cost competitive the buyer perceives the particular supplier to be. The price criteria will not usually be used to factor the bidding amount.

[0543] The factor is calculated by firstly determining the maximum score that a supplier can achieve for a particular subcategory i.e. a particular panel. For the Toyota example the maximum score possible is 210. This is calculated by multiplying the buyer rating for each criteria with 10 (the maximum possible score that a supplier can achieve for a particular criteria), then adding the individual criteria score to get the total 210. Quality has a buyer rating of 7, which gives 70 when multiplied by 10. 70 added to delivery of 80 and service of 60 gives a total of 210.

[0544] Once the total denominator (210 in the Toyota example) is calculated, the total for each supplier is calculated in a similar way. This time, however, rather than multiplying the rating by 10, it is multiplied by the actual score assigned for that criteria to the individual supplier. For Dunlop as an example, quality has a rating of 7 which, when multiplied by Dunlop's score for quality of 7, gives a total score for Dunlop's quality of 49. The 49 is added to the score for delivery and service to give a total for Dunlop of 163. This score of 163 for Dunlop is now divided by the total for the panel (210), to give a factor of (163/210) or 0.776 for Dunlop.

[0545] This factor of 0.776 is critical to Dunlop, as the factor is used to scale Dunlop's bid during a bidding event. Dunlop may pay the price for low scores on quality, service etc by finding it more difficult to win business from Toyota. Or Dunlop's profitability is being impacted (by having to bid lower for new work) because it has not paid attention to all the supply criteria.

[0546] The factor value is only important when considered in the context of how much of a handicap it presents for a particular supplier when compared to the other supplier in the panel. So the relative factor value is more important than the absolute value.

[0547] This factor and the ratings and criteria are visible to Dunlop, which allows Dunlop to work with the buyer to improve their assigned factor.

[0548] Over time the administrator computer will collect data on all the supply criteria. This will allow the administrator computer to help buyers make decisions about how to rate a particular supplier. For example the administrator computer will measure payment time, and delivery time automatically from the buyer's ERP system. This data will be analysed and presented to the supplier as an input to the supplier rating process.

[0549] An example algorithm for carrying out the factored bidding process is described below. The following terms are used. Term Definition Value Range SB Submitted Bid SB > 0 CBTW Current Bid To Win CBTW > 0 SP Starting Price SP > 0 FB Factored Bid FB > 0 MD Minimum Decrement MD > 0 SF Supplier Factor SF > 0 n Global bid number ie 1^(st) bid, 2^(nd) bid n ≧ 1 where n = 1, 2, . . . m Individual supplier bid number m ≧ 1 X Supplier ‘X’

[0550] Bidding Logic

FB₁=SP

[0551] This merely states that the first (calculated) factored bid should also equate to the starting price, to accommodate the following formulas.

FB _(n) =SBx _(n)+(MD/SFx)−MD

[0552] [note FB_(n)=SBx_(n) where SF=1.0]

[0553] All submitted bids are transformed via the above formula using the corresponding supplier factor. This formula ensures that the rules of decreasing bids hold for running a reverse auction based on the Factored Bid. The case for SF=1.0 simply means that the factored bid is equal to the submitted bid. This represents a notional ‘perfect’ supplier.

SBx≦CBTWx

[0554] Given that there is a minimum bid decrement (to avoid immaterial bids) and that the supplier submitted bids are factored, it is unlikely that suppliers will be able to readily calculate their next bid in order to hold the current bid. For this reason, an additional informational field is required and is labeled ‘Current Bid To Win’. This field is related directly to the supplier factor and effectively tells a supplier the maximum that they can enter as a submitted bid. In turn this is factored and results in them winning based on the current factored bid. This also reduces the chance of them having to enter multiple bids whilst effectively guessing where they have to bid to win the business. Of course, it is possible that Supplier X will not win the bid if Supplier Y also enters a bid a split second before, since now CBTWx has been recalculated.

CBTWx _(m) =FB _(n−1)−(MD/SFx)

[0555] where n≧2 and CBTW>0

[0556] In order for the suppliers to make bids with the best chance of winning, they need some guidance via a ‘ready reckoner’, since their raw submitted bid is always factored and may result in them making an uncompetitive bid. The premise of factored bidding is that suppliers with higher ratings can bid higher amounts than those with lower ratings and still win the business. The above formula achieves this effect by factoring the minimum decrement then subtracting this from the last factored bid to calculate the bid to win the business.

[0557] Under this scenario, if Supplier 1 has a higher factor than Supplier 2, (MD/SFx)₁<(MD/SFx)₂, meaning that Supplier 1 can enter a higher bid (CBTW_(1n)) and win the business from Supplier 2 with CBTW_(2n).

[0558] The form of this equation ensures that the relative difference between suppliers is maintained at all levels of bidding. This reflects associated fixed cost differences such as freight, that are payable irrespective of the winning bidder, if prices are quoted FOB (Free On Board) for example.

[0559] In the system developed using the factored bidding technique, the following points apply:

[0560] All the above calculations are performed to at least six (6) decimal places. This avoids rounding errors which may have a material effect.

[0561] The active pages include the fields of ‘Submitted Bid’ and ‘Factored Bid’.

[0562] Entries only appear in a ‘Submitted Bid’ field if the supplier logged on to the system holds the current factored bid. This is also indicated by a green traffic light symbol in the Status field.

[0563] An additional field called ‘Current Bid To Win’ is included on the screen. This is a display only field and is calculated separately for each supplier.

[0564] The Bid History includes fields for ‘Submitted Bid’ and ‘Factored Bid’. The Factored Bids are shown for all bids. The Submitted Bids are only shown for the bids of the supplier's logged in.

[0565] 10. Time extensions—Best and Final Price

[0566] In general, an online bidding event is run for a fixed period of time (such as thirty minutes). At the end of this time, as measured by the server clock, the lowest factored bid is accepted. The use of a fixed period of time contributes to the efficient price discovery mechanism of the process, and encourages bidders (suppliers) to enter their bids within this prescribed period (which is published in advance). By limiting the entire event to a reasonably short period, bidders are encouraged to actively view and participate in the event, rather than simply to enter a bid then logoff.

[0567] In certain situations, the bid submission may be affected by the participants' physical ability to respond. The success of a bidder may be dependent on the dexterity and nerve of the participating suppliers, and when dealing with substantial contracts, this effect can tend to compromise the desired intent of providing an efficient and transparent mechanism for trading, whereby each supplier has the opportunity to submit their best offer in response to real-time competitor actions. This effect can mean that the buyer may not receive the very best offer possible, because the event time may expire before a counter bid can be made.

[0568] For the above reasons, it is possible to include in certain online auctions the function of an automatic extension of the event duration, if a bid is received within a specified window at the close of the event (typically five minutes). The event is then extended by say, an additional fifteen minutes. It is, however, important that events represent a credible trading environment for buyers and sellers, and the rules of the system must be clearly communicated to all participants. It is also important that the process be kept rapid and efficient, and that, at the conclusion of the event, the result is known immediately. This time extension capability is particularly useful with high value, strategic materials where significant shifts in the bidding activity can occur in the final stages of an online event.

[0569] The time extension, which is an integer number in minutes, may be chosen as an option by the party creating a BOM, eg by ticking a button to indicate that this option is to be activated for a particular event. The default option selects <TIME EXTENSION NOT SUPPORTED>. An indication that the option has been selected will appear on all screens containing the market rules of the bidding event.

[0570] A further parameter is required to indicate when the time extension is to be activated, the <ACTIVATION PERIOD>. This is the time prior to the close of bidding in which a submitted bid causes the event to be extended by one extension period. A logic check is applied to ensure that the activation period is less than (but not equal to) the extension period. The activation period should have a label of <ACTIVATED DURING LAST:> and a suffix of <MINUTES>.

[0571] There is no limit on the number of extension periods, but the application can include an additional parameter to specify <MAXIMUM NUMBER OF PERIODS>, which has a default value of <NONE> displayed. The bid extension time extends from the <BID END TIME> of the original to the current end time of the current extension period.

[0572] The original <BID END TIME> appears on the screen in its standard form, and in order to indicate that an extension occurred historically, an additional ‘Extension Period’ column is added to the history screen, populated by the total number of minutes for all the extension periods that have been triggered.

[0573] The bidding logic should operate as follows when the time extension option is activated for a particular BOM:

[0574] If a bid is submitted within the activation period, the bidding event continues for an amount of time equal to the extension period.

[0575] The ‘Time Remaining’ for the event is reset and counts down from the extension period.

[0576] A suitable indicator should makes clear to the user that the bidding event is into the extension period. The normal bidding logic in terms of current bid to win, minimum decrement and factored bid should apply to the time extension period.

[0577] As explained above, in an online bidding event the best price may not be achieved, due to suppliers being unable to submit their real ‘best and final’ price before the expiry of the fixed duration. The ‘auto-extend’ function described above is one way of mitigating this problem.

[0578] An alternative approach, referred to herein as the ‘Best and Final Bid’ function, applies a systematic approach, wherein suppliers who have submitted a bid during the course of the normal bidding event are given the opportunity to submit a ‘best and final bid’ (BAF) once the event has concluded. A preferred set of rules for this process is as follows:

[0579] Only suppliers who have submitted bids during the course of the bidding event are eligible to submit a BAF.

[0580] The buyer is able to determine how many bidders are included in the BAF. For example, the three suppliers with the lowest factored bids at the end of the normal bidding time may be eligible.

[0581] Assuming three eligible suppliers, the suppliers with the two highest factored bids are each presented with the option of submitting a BAF at the end of the event (ie after the bidding time has elapsed according to the server clock). It is not mandatory to submit a BAF, even if the supplier is eligible to do so. In order to preserve the concept of factored bidding, each supplier is presented with their CBTW (Current Bid To Win) as in the normal bidding event described above. Each of these suppliers can then submit a bid, which is factored as normal to result in a factored bid.

[0582] It is only possible for each supplier to submit one BAF bid, at or below their CBTW.

[0583] After a suitable elapsed period (eg. one minute), the option to submit a BAF for these bidders is removed.

[0584] The lowest factored bid from this process is then used to calculate the equivalent submitted bid for the supplier with the lowest factored bid from the normal bidding event.

[0585] This remaining supplier is then presented with the option of submitting a BAF, based on the calculated submitted bid as above. In this case, the supplier is presented with a CBTW value which they need only match to win the business. In this way, the relativity amongst suppliers is preserved throughout the entirety of the event. In this way, to encourage the function is not abused, the supplier with the lowest factored bid during the normal event is rewarded with the ultimate BAF option.

[0586] 11. Reserve Price

[0587] With factored bidding, once a supplier submits a suitable bid, the buyer is bound to accept it and award a contract. This necessitates the buyer having to set a starting price that is often too low to attract any supplier bids, which can also arise when the buyer does not solicit any indicative pricing from suppliers prior to the event and the expectations between buyer and supplier vary widely. There is also a desire to make the online bidding process more closely resemble a true negotiation, whereby both parties may have quite different opening positions.

[0588] For this reason, it is desirable to have the ability to solicit indicative prices from suppliers prior to setting the starting price for a bidding event. Without resorting to performing a full-blown RFQ, this can be achieved during the BOM Validation phase. Based on the prices received from suppliers, the buyer has better information with which to set his starting price. It is also desirable for the buyer to have the ability to set a reserve price, above which he is not bound to accept any offer.

[0589] When a reserve price is set, the transparency and fairness of the process must be firmly adhered to in order to engender supplier acceptance.

[0590] The system requires that a reserve price is always set prior to a bidding event. The reserve price may be set or changed up until the BOM becomes Active. Since some material prices are highly volatile, it is desirable to leave the setting of the reserve until as close to the time when the BOM becomes active as possible. A parameter is indicated on the ‘Market Rules’ page where the buyer provides an indication of the number of hours before the start time that the BOM is activated (and thus transferred to the active page).

[0591] The rules relating to the reserve price are as follows:

[0592] The reserve is not disclosed to the suppliers until it is reached during the course of a bidding event

[0593] Once the reserve price is reached, the contract will be awarded to the bidder with the lowest factored bid at the close of the bidding event.

[0594] If the reserve is not reached, the buyer has the right not to proceed with any contract; if however the buyer chooses to proceed with awarding a contract, he must do so with the bidder holding the lowest factored bid at the close of the bidding event. The rules surrounding the event must preclude any post-event negotiation. This is necessary to retain the credibility, transparency and fairness of the process.

[0595] Once the reserve price is reached during the course of an online bidding event, this is indicated to all suppliers by an appropriate indicator or message on the Active screen.

[0596] 12. Request for Opening Bid

[0597] Generally, the buyer initially specifies a starting price for a bidding event, which effectively becomes the first factored bid from which each supplier's CBTW is then calculated (see above). The starting price is required as an input to calculate the factors for each supplier. Even if the starting price subsequently changes, the relative difference between the suppliers will remain the same (assuming their factors do not change from those initially calculated).

[0598] In order to have a more market-driven starting price, the suppliers may be required to submit a contractual price when they validate the BOM. This quoted price is then treated as their first submitted bid, and from this the corresponding factored bid is calculated. The lowest factored bid—based on the first submitted validation bid of each supplier—will be calculated when each supplier validates, and this becomes the new starting price. The bidding event therefore commences with a starting price equal to the lowest factored bid from the panel of suppliers who have validated the BOM. The CBTW for the supplier with the lowest factored bid, for example, will thus be his first submitted bid, less the minimum decrement.

[0599] In some cases, a very low quote may be returned (eg supplier dumping price), that could invalidate the event. In this case, the Buyer needs the ability to override the starting price. This would only be possible via a separate menu option, prior to the BOM becoming activated. The menu option should be labeled ‘Override Starting Price’. This would take the Buyer to the ‘Market Rules’ page with only the ‘Starting Price’ field open for editing.

[0600] 13. Factored Pricing

[0601] The factoring concept described above can be extended to factored pricing. Generally, such an approach is associated with RFQs, whereby the buyer specifies the criteria that is important for a particular material category/sub-category, and then rates each supplier against these. In this way, the buyer can set an acceptable price for the material, and then the respective suppliers' factors are applied to this price to arrive at a factored price for each supplier.

[0602] Suppliers are notified via email of this factored RFQ, which is then open for a limited time. During this time, suppliers can log onto the system website and view the details of the RFQ as well as their factored price. They then have the option of accepting the conditions of the RFQ at (or below) the suggested price. This price is used as a final price that forms the basis of the contract, if it is accepted by the supplier.

[0603] Once a supplier accepts the RFQ conditions and the price, the buyer is notified and can compare responses by multiple suppliers. The selection of a winning supplier can be automated for purely ‘factored’ information, although it is likely that the buyer would do this manually in the first instance. Alternatively, the buyer can set the factors and rate each supplier, then set a benchmark price which is scaled for each supplier based on their factoring information. Each supplier who logs in sees their respective factored price for the BOM specified, and can choose to accept that price or submit a lower price. Now the buyer has the option of either setting a rule whereby the first accepted response by a supplier at or below their factored price will win the business, or a rule whereby the buyer then has the option to choose the best deal (eg. the supplier that sets the price with the largest margin below their factored price).

[0604] A variation on this is that the buyer specifies criteria, each with suggested values. An example of this would be: Payment Terms  7 days 14 days 30 days 60 days

[0605] The buyer may choose one of these values and make it mandatory i.e. cannot be varied in the response by the supplier. Alternatively, the buyer may suggest a value (eg 60 days) but leave it open so that the supplier can modify the value (eg 30 days). This could then be used by the buyer, once the response has been received, in awarding the RFQ to a particular supplier. Alternatively the buyer chooses to show the various factors to the respective suppliers, along with the associated options, and leaves it to the supplier to select an option. In this way the supplier is effectively self factoring.

[0606] Once a value is selected, the system may be arranged to automatically factor the supplier on their response, so that competing responses can be compared and ranked by the system.

[0607] If several suppliers respond by accepting the RFQ conditions, and their factors are within an acceptable range to the buyer, a bidding event for the business could follow the RFQ process. In this case the buyer is setting factors based on known information about the suppliers. This is especially important if the buyer has not worked with a particular supplier before, or if the buyer is purchasing a material type for the first time. The buyer is using the factored pricing functionality as a discovery process for the factored bidding event. This will be most important for project based industries in which one-off designs are prevalent or where timing of material purchases is more sporadic than manufacturing based industries.

[0608] A worked example of this process is shown below: Buyer Specification Stainless Steel Tape Delivery schedule Business Rules Type 304D 2Bfinish 1 March 20 tonnes Delivery Terms FIS Size 305 mm x 0.8 mm 10 April 20 tonnes Payment Terms 60 days Quantity 60 tonnes 25 May 20 tonnes Base price /kg $4.00/kg Roll weight 2000 kg

[0609] Suppliers

[0610] After factoring suppliers in the same way as for factored bidding, this is then applied to the buyer's target price to arrive at a price for each supplier as shown in the table below: Factored Price Supplier Factor Base Price ($/kg) ($/kg) Supplier 1 1.00 4.00 4.00 Supplier 2 0.95 4.00 3.80 Supplier 3 0.84 4.00 3.36

[0611] Once a supplier accepts the factored price together with the associated specification and commercial terms, the buyer is able to choose to award the business to that supplier.

[0612] Where a supplier has the ability to select some of the terms (eg payment terms) or to vary the specification (eg quality), this may affect their factor. In the first instance, a buyer may choose to revise a supplier's factor on this particular attribute which would affect their overall rating for that material and hence their factored price. This process could be automated, so that as the supplier selects varying terms, the factored calculation is done by the system immediately. Here the relationship between the selection values and the resultant factoring is stored by the system. This approach therefore allows the supplier to effectively perform some ‘what if’ analysis when selecting the available options from the specifications.

[0613] This invention provides a fundamentally different approach to the conventional ‘reverse auction’ concept, and allows a participating organisation's budget for strategic materials contracting to be employed in a highly cost-effective manner in a competitive online bidding process, whilst reducing the time for ‘price discovery’ in comparison with the conventional RFQ process.

[0614] In traditional reverse auction processes for strategic material supply, the vendors compete on price and the buyer then somewhat arbitrarily chooses the winner after the event based on what can be a laborious evaluation of criteria other than direct pricing. The problem with this approach, apart from the time it takes, is that it destroys the credibility of the bidding event, since the lowest bidder may not necessarily win the contract. The present invention addresses this drawback of the conventional methodology.

[0615] As previously mentioned, the invention in its various forms gives a business buyer access to a potentially powerful web based procurement application that may be completely internally controlled by the buyer.

[0616] The present invention may be applied to the procurement process for any goods or services which are sufficiently valuable (to justify use of the process), specifiable (so that competing suppliers are able to interpret the requirements, and to afford a consumer basis for comparison), and contestable (ie more than one supplier has the capability to fulfil the request). Although the examples given in this description relate to ‘direct’ material, used as direct inputs to a manufacturing process, the invention is equally applicable to ‘indirect’ inputs (travel, freight, consumables, etc.).

[0617] The word ‘comprising’ and forms of the word ‘comprising’ as used in this description does not limit the invention claimed to exclude any variants or additions.
